BASIC RESIST STRIPPING:
The Key Parameters for BASIC RESIST STRIPPING are:
• Chemistry: The make-up and concentration of the selected chemistry.
• Time: How long the metal remains in the bath
• Temperature: Changes in ambient temperature
• Bath Life: Dilution of chemistry and/or contaminates in the solution
• Bath Agitation: Improving the surface exchange of chemistry by fluid movement
